Question 967693
Total bill = $110
Fixed charge = $35 (charged just for driving to your house)
Then, what was charged for the hours worked is
$110 - $35 = $75 .
If those $75 were the charge for 3 hours of work,
then what the plumber charges for each hour of work is
{{{"$75"/3="$25"}}}
The plumber's hourly rate is {{{highlight("$25")}}} .
